I asked my dentist where she buys her toothbrushes that she gives to clients. And, she told me she gets them through a website called Practicon. I checked it out and they have some toothbrushes on clearance, which would make them just $0.25 each after you pay shipping charges. Head over to Practicon and check out their clearance section. They have 144 toothbrushes for $29.99 (plus $6.99 shipping). I’m having such a hard time finding deals on toothbrushes this year, I think I will probably end up buying mine online. These are really nice quality and should last the child who receives them for quite a while.
Another option is to look at Venture Six.
